Claus-Dieter sent me information on a new product that he built along with Dieter Wächter of Nocrotec.com fame. This new gadget is is a two digit thermometer based on IN-16 Russian Nixie tubes. The tubes are lit from underneath with a blue LED and there is a neon lamp that acts as a negative sign indicator. The temperature sensor is a Dallas DS18S20 on 1, 2, 5, and 10 meter lengths. This device supports up to two sensors so you can have the device can report both indoor and outside temperature.
The clock has a nice small design with all of the components hidden on the underside of the board. The clock enclosure is up to the user to design.
The software has a few neat features too. It has a smart menu system that makes operation easy. The user can adjust the update frequency and error detection settings. Additionally, the device has a built in cathode poisoning prevention mechanism; the device cycles through digits in a simulated slot machine effect to prolong the life of the IN-16s.
